B1C4C
B1C4C-1ST ROW PASSENGER SEAT BELT BUCKLE PRETENSIONER CIRCUIT LOW
For a complete wiring diagram, refer to the wiring information Electrical Diagrams.
- When Monitored:
With the ignition on, the Occupant Restraint Controller (ORC) monitors the resistance of the Passenger Seat Belt Buckle Tensioner circuits.
- Set Condition:
The ORC has detected low resistance on the Passenger Seat Belt Buckle Tensioner circuits.
1. VERIFY ACTIVE DTC
NOTE: Make sure the battery is fully charged.
NOTE: The scan tool, SRS Load Tool Kit 8443, and DVOM are required to perform the following test.
1. With the scan tool, read the ORC DTCs.
Does the scan tool display B1C4C-1ST ROW PASSENGER SEAT BELT BUCKLE PRETENSIONER CIRCUIT LOW DTC?
Yes
- Go To 2
No
- Perform the AIRBAG SYSTEM INTERMITTENT TEST. .
2. CHECK FOR SHORTED PASSENGER SEAT BELT BUCKLE TENSIONER CIRCUIT
WARNING: Turn the ignition off disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
1. Disconnect the Passenger Seat Belt Buckle Tensioner connector.
NOTE: Check the connectors - Clean and repair as necessary.
2. Connect the SRS Load Tool Kit 8443 and SRS Load Tool Jumper 8443-20 to the Passenger Seat Belt Buckle Tensioner connector.
WARNING: Turn the ignition on, then reconnect the 12-volt battery. Wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
3. With the scan tool, read the ORC DTCs.
Does the scan tool display B1C4C-1ST ROW PASSENGER SEAT BELT BUCKLE PRETENSIONER CIRCUIT LOW DTC?
Yes
- Go To 3
No
- Replace the Passenger Seat Belt Buckle Tensioner.
- Perform the AIRBAG SYSTEM VERIFICATION TEST. Airbag System Verification Test.
3. CHECK (R56) PASSENGER SEAT BELT BUCKLE TENSIONER LINE 1 CIRCUIT AND (R54) PASSENGER SEAT BELT TENSIONER LINE 2 CIRCUIT FOR A SHORT TO GROUND
WARNING: Turn the ignition off disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
1. Disconnect the SRS Load Tool Kit 8443 and SRS Load Tool Jumper from the Passenger Seat Belt Buckle Tensioner connector.
2. Disconnect the ORC connectors.
NOTE: Check the connectors - Clean and repair as necessary.
3. Connect the SRS Load Tool Adapter 8443-32-R to the ORC connectors.
NOTE: The IP Harness is always connected to the right side (C1) of the 8443-32-R Adapter.
4. Measure the resistance of the (R56) Passenger Seat Belt Buckle Tensioner Line 1 circuit between the Passenger Seat Belt Buckle Tensioner connector cavity 2 and ground.
5. Measure the resistance of the (R54) Passenger Seat Belt Buckle Tensioner Line 2 circuit between the Passenger Seat Belt Buckle Tensioner connector cavity 1 and ground.
Is the resistance below 10K Ohms on either circuit?
Yes
- Repair the Passenger Seat Belt Buckle Tensioner circuits with a resistance below 10K Ohms for a short to ground.
- Perform the AIRBAG SYSTEM VERIFICATION TEST. Airbag System Verification Test.
No
- WARNING: If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to follow these instructions may result in possible serious or fatal injury.
- Replace the ORC.
- Perform the AIRBAG SYSTEM VERIFICATION TEST. Airbag System Verification Test.
